We report detailed clinical and histopathologic findings of a fatal case of DRESS syndrome resulting from antiepileptic drug treatment that was accompanied by severe enterocolitis, malabsorption, and cachexia. Griscelli syndrome type 2 (GS2) is an autosomal recessive condition associated with the development of hemophagocytic lymphohistiocytosis. Pancytopenia refers to a deficiency in all of our three major types of blood cells.1 Specifically, these include: 1. Pancytopenia has been reported in a patient taking valproate and risperidone (146 A ) . Lamotrigine (LTG) [3,5-diamino-6-(2,3-dichlorophenyl)-1,2,4-triazine] is a novel anticonvulsant chemically unrelated to current antiepileptic drugs and with a pharmacological profile similar to that of phenytoin. The first case was from an anorectic and depressed Would you like email updates of new search results? The radiolabeled material in skin (15.6 +/- 1.4%) was almost entirely [(14)C]lamotrigine. For this purpose the following patient groups were compared: VPA monotherapy, VPA + one enzyme-inducing AED, VPA + LTG, and VPA + LTG + one enzyme-inducing AED. This syndrome can range from mild cutaneous rash to drug reaction with eosinophilia and systemic symptoms that include fever, rash, lymphadenopathy, pancytopenia, and involvement of multiple internal organs. No evidence of infection was evident. A Mysterious DRESS Case: Autoimmune Enteropathy Associated with DRESS Syndrome. We aimed to report this case in the literature and make … Along with epilepsy, it has become the treatment of choice in many areas of medicine, including various psychiatric disorders and pain syndromes. The ratio of perforin to CD3(+) lymphocytes was assessed on immunostained LB sections. Since we now have significant paediatric literature on each of these agents, we provide a comprehensive and current literature review of the newer AEDs, focusing on safety and tolerability data in children and adolescents. The increase CYP metabolism of LTG in children could result in increased formation of the reactive metabolite and a higher incident of rash. Epub 2017 Nov 26. Due to aggressive course, awareness of HLH signs and symptoms is crucial among physicians for the early diagnosis and immediate introduction of adequate HLH treatment. To assess the association between exposure to antiepileptic drugs and aplastic anemia has been the subject of a retrospective case–control study (173 cases and 497 controls) using data from the UK General Practitioners Research Database (GPRD) (145 C).Antiepileptic drug use was more prevalent among … Oxcarbazepine treatment was terminated after the intravenous immunoglobulin treatment. ICI-related haemophagocytic lymphohistiocytosis (HLH) has been recently outlined in single case reports, raising a concern about the need of increasing our knowledge on this rare yet life threatening ICI haematological toxicity. Kırık S, Güneş H, Yurttutan S, Sarışık N, Acıpayam C, Kırık Y. Hemophagocytic lymphohistiocytosis associated with oxcarbazepine. The second We present the case of 2 sisters who had vastly different phenotypic presentations despite having the same genetic frameshift mutation in the RAB27A gene. Most cases of VPA hepatotoxicity occurred in children younger than 2 years who had preexisting neurologic or other physical defects. This review concentrates on current literature concerning serious and life-threatening ADRs. Summary: Purpose: To assess the association between exposure to antiepileptic drugs (AEDs) and the occurrence of aplastic anemia. Women are more susceptible to this drug reaction, which indicates the role of sex hormones in the pathogenesis of ACHS [3, 5, 6]. For the analysis of variance, the VPA serum concentration in relation to VPA dose:body weight (level:dose ratio, LDR) was calculated and compared for different drug combinations. Sepsis, tuberculosis, or fungal infection can cause pancytopenia. A clinically characteristic hypersensitivity reaction to phenytoin occurred in two patients three to four weeks after they started phenytoin therapy. Vigabatrin has been reported to cause seizure aggravation, especially in myoclonic seizures. Aplastic anemia – acquired aplastic anemia is the #1 cause of pancytopenia, but remains rare with an incidence of 2 cases per million people in developed countries. Of six patients treated with lamotrigine, five have improved substantially, but only one is in sustained complete remission. The literature related with lamotrigine use for the treatment of different psychiatric disorders has been reviewed in this paper. [Hemophagocytic syndrome with hemophagocytes in the peripheral blood]. Infants and children have higher concentration ratios of 4-ene-VPA to VPA. Does Lamotrigine Influence Valproate Concentrations? moderate basophilia (2.3×109/l) and a normal azurophil count (4.1×109/l) but with approximately 66% of the azurophils containing phagocytosed erythrocytes. Basic scientists, clinical pharmacologists and neurologists from 24 countries attended the conference, whose main themes included a focus on status epilepticus (epidemiology, current and future treatments), evidence-based treatment guidelines and the potential of neurostimulation in refractory epilepsy. The treatment of pancytopenia depends on the cause. Hypotheses regarding the pathogenesis of the hepatotoxicity include preexisting mitochondrial disease or inborn errors of metabolism, VPA inhibition of beta-oxidation, and toxicity from VPA metabolites VPA, 4-ene-VPA, and 2,4-diene-VPA. This syndrome can range from mild cutaneous rash to drug reaction with eosinophilia and systemic symptoms that include fever, rash, lymphadenopathy, pancytopenia, and involvement of multiple internal organs. The most common idiosyncratic reaction to lamotrigine (LTG) is rash, affecting 10-20% of patients. To determine ICI-related HLH clinical, haematological, and coagulation features, its timing and outcome, concurrent irAEs and concomitant infections, we performed a retrospective observational cross-sectional study and queried VigiBase, the WHO global database of suspected adverse drug reactions (ADRs), on September 30th, 2018. There have been rare reports of other neurological ADRs to vigabatrin, such as encephalopathy, aphasia and motor disturbances. Children often received higher milligram per kilogram doses compared with adults. Features that distinguish hemophagocytic lymphohistiocytosis from other disorders, such as malignant histiocytosis, X-linked lymphoproliferative disorder, congenital immunodeficiency states, the accelerated phase of Chediak-Higashi syndrome, and cytophagic histiocytic panniculitis, which may be associated with a hemophagocytic syndrome, are presented. Case report: Consistent with previous formats of this conference, the central part of the conference was devoted to a review of AEDs in development, as well as updates on marketed AEDs introduced since 1989. GS2 is known to have immunologic compromise and oculocutaneous albinism. It is possible that it increased the clinical awareness for these mild forms in immune-competent patients could account for the improved recognition of atypical cases with favorable outcome. Although only 36% of patients with this histologic lesion had a complete HS (association of fever, splenomegaly, bicytopenia, hypertriglyceridemia, hyperferritinemia, and/or hypofibrinogenemia), almost all patients had similar underlying diseases (human immunodeficiency virus infection, malignant hemopathy, and autoimmune disease) and/or acute ongoing infections (tuberculosis, cytomegalovirus, and Epstein-Barr virus). Conclusions At concentrations up to 300 microM, LTG had no effect on potassium-evoked amino acid release or on spontaneous release. The pathological hallmark of HLH is phagocytosis of blood cells and platelets by activated macrophages and histiocytes. As the response to treatment and long term outcome are much poorer, it is important to differentiate myoclonic absences from typical childhood absence epilepsy. In addition, anti-epileptic drugs and anti-cancer drugs are known to cause HLH (Lambotte et al. Arch Pathol Lab Med. discontinuation of lamotrigine; the hemogram and liver function profile improved dramatically. Kuwata K, Yamada S, Tsuda H, Asou N, Naito M. J Immunother Cancer. Ross CW, Schnitzer B, Weston BW, Hanson CA. Levetiracetam can cause several adverse effects predominantly related to the central nervous system including dizziness, headache, behavioural changes and somnolence. As there was neither disease activity of RA nor associated infection throughout the clinical course, bucillamine was suspected of being the cause of HPS in our patient. To date approximately 4000 adults >12 years of age have been treated with lamotrigine in Glaxo Wellcome sponsored clinical trials. Clinical response, rather than drug levels, should guide dosage changes. As the infected cells are targeted, the normal cells are also damaged in some proportion, which causes pancytopenia. Infections. One month later he suffered from impaired liver function and pancytopenia in the presence of hypocellular bone marrow with hemophagocytosis. However, pancytopenia, though exceedingly rare, is a potentially life … One month later he suffered from impaired liver function and pancytopenia in the presence of hypocellular bone marrow with hemophagocytosis. 31 (82%) cases defined ICI-related HLH outcome, which resolved in 19 (61%) cases. Hemophagocytic syndrome should be considered a possible cause of pancytopenia in patients taking new antiepileptic drugs such as lamotrigine. Most of the reported adverse events seen in lamotrigine treated patients in all studies were judged by the investigator to be mild or moderate in severity; few of the adverse events resulted in the withdrawal of patients from studies. The literature contains only very few reports of drug reaction with eosinophilia and systemic symptoms complicated by hemophagocytic lymphohistiocytosis. Here, we present a case of a young woman with DRESS syndrome following exposure to vancomycin with renal, cutaneous, and gastrointestinal involvement. Lamotrigine (LTG) is an antiepileptic drug (AED) recently released in several countries. Risk of serious rash may possibly be lessened by strict adherence to manufacturer's dosing guidelines, particularly in patients who are at higher risk: those on concurrent VPA and in the pediatric population. The surgical and autopsy pathology features infiltrates composed of lymphocytes and ordinary, but activated, histiocytes and hemophagocytosis. It is difficult to predict the prognosis or clinical course of secondary hemophagocytic lymphohistiocytosis (HLH) due to the various underlying causes. The aim of this study is to investigate the effect of lamotrigine (LTG) on valproate (VPA) concentrations dependent on LTG dose, LTG concentration, and additional enzyme-inducing antiepileptic drugs (AED) as well. Machaczka M, Vaktnäs J, Klimkowska M, Nahi H, Hägglund H. Med Oncol. Many questions regarding the nature of this potentially serious ADR remain unanswered, as no prospective controlled study examining the phenomenon has been published. Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome of pathologic immune activation. Iatrogenic causes of pancytopenia include chemotherapy for malignancies if the drug or drugs used cause bone marrow suppression.Rarely, drugs (antibiotics, blood pressure medication, heart medication) can cause pancytopenia.For example, the antibiotic chloramphenicol can cause pancytopenia in some individuals.. It arises as hereditary forms, or acquired, during viral, autoimmune or malignant diseases, and is usually a disorder with fulminant course and high incidence of lethal outcome. COVID-19 is an emerging, rapidly evolving situation. Haemophagocytic lymphohistiocytosis in patients treated with immune checkpoint inhibitors: analysis of WHO global database of individual case safety reports. Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) is a rare but potentially life-threatening cutaneous hypersensitivity reaction characterized by extensive mucocutaneous eruption, fever, hematologic abnormalities, and extensive organ involvement. Treatments for pancytopenia include: drugs to stimulate blood cell production in your bone marrow. Discussion: Further, four days after discontinuation of allopurinol, in view of the laboratory signs of bicytopenia, hyponatremia, hypertriglyceridemia and hyperferritinaemia, as well as the presence of hemophagocytosis in bone marrow, a diagnosis was made of lymphohistiocytosis hemophagocytic syndrome complicating a drug reaction with eosinophilia and systemic symptoms. For statistical evaluation, regression analytical methods and an analysis of variance were performed. Zhonghua Min Guo Xiao Er Ke Yi Xue Hui Za Zhi. Lymphocytes and macrophages (sometimes with hemophagocytic activity) accumulate in bone marrow, spleen, liver, or lymph nodes. Causes. Accessibility Few case reports have been published regarding pancytopenia associated with levetiracetam treatment, and its intrinsic pathogenesis is still unknown. Over the years, skin rash also been identified as a hypersensitivity reaction to phenytoin. The newer antiepileptic drugs (AEDs) provide more therapeutic options and overall improved safety and tolerability for patients. The importance of recognizing this syndrome is stressed because it is potentially fatal. However, there can be several different underlying causes. Lamotrigine can be bioactivated to an arene oxide by rat hepatocytes in the absence of a major competing pathway such as N-glucuronidation. Due to aggressive course of sHLH, increased awareness is indicated in all patients with malignancies which develop unremitting fever, cytopenia and splenomegaly. More recently, antiepileptic drugs were associated with HLH onset, because of their immune-modulating action, ... Our patient, described in this paper, probably developed HLH already 3 months after APSCT, but local myeloma progression and, although less likely, antiepileptics could play a role (e.g. Intravenous immunoglobulin and steroid were administered with, Access scientific knowledge from anywhere. g. Overwhelming infections. Two or more serum samples from the same patient were considered only if the comedication had been changed. Dieter Schmidt, Stefan Beyenburg, in Side Effects of Drugs Annual, 2009. To read the full-text of this research, you can request a copy directly from the authors. LTG inhibited veratrine-evoked release of glutamate and aspartate, with ED50 values of 21 microM for both amino acids, but LTG was less potent in the inhibition of GABA release (ED50 = 44 microM). Detoxification of non-arene oxide metabolites (e.g., of acetaminophen) was normal in patients' cells. Treatment was highly variable, although most initiated systemic corticosteroids with/without IVIG, plasmapheresis, or etoposide. The clinical features and laboratory tests of two patients fulfilled the criteria of HLH, whereas the other patient had initiated therapy before fulfilling the criteria. The diagnosis of virus-associated hemophagocytic syndrome with mild clinical course and seemingly spontaneous improvement was established, although it did not fulfill all proposed diagnostic criteria. Zhonghua Min Guo Xiao Er Ke Yi Xue Hui Za Zhi. Chronic active Epstein-Barr virus infection and virus-associated hemophagocytic syndrome. The diagnosis of drug hypersensitivity was suggested and was confirmed by histological examination of a skin biopsy. Results In addition, a subgroup of 40 patients was analyzed to see whether changing the LTG dose influences VPA serum concentrations. Calculator: Absolute neutrophil count; RELATED TOPICS. Phenytoin alone was not toxic to cells. A CYP-catalyzed arene oxide intermediate of LTG has been identified. Liu DL, Teng RJ, Ho MM, Hwang KC, Hwang LM. Lamotrigine is a novel anticonvulsant drug which has multiple mechanisms of action. In addition, nonlinear regression analysis confirmed that patients on enzyme-inducing AED (carbamazepine, phenytoin, phenobarbital, methsuximide) had significantly lower VPA concentrations. Gender had no significant influence on VPA serum concentration. Antiepileptic drugs (AED) are medications given to control epileptic seizures and convulsions. Pancytopenia resulting from drug-induced hemophagocytosis has been reported in glycopeptide and trimethoprim-sulfamethox-azole [2]. Case report, Safety Review of Adult Clinical Trial Experience with Lamotrigine, Lamotrigine-Associated Rash: Risk/Benefit Considerations in Adults and Children, Adverse Reactions to New Anticonvulsant Drugs, Metabolism of Lamotrigine to a Reactive Arene Oxide Intermediate, Children Versus Adults: Pharmacokinetic and Adverse-Effect Differences. Fourteen cases (61%) clinically worsened despite initial therapy, prompting a workup with diagnosis of HLH on average 2.3 weeks after diagnosing DRESS. 4 Congenital – Fanconi anemia, dyskeratosis congenita, Shwachman-Diamond syndrome, GATA2 associated syndromes, Amegakaryocytic thrombocytopenia The safety and tolerability of newer antiepileptic drugs in children and adolescents. 1991 May;115(5):470-4. The literature related with lamotrigine use for the treatment of different psychiatric disorders has been reviewed in this paper. ICI-related HLH showed clinical, haematological and coagulation features similar to those of HLH with different etiology. The Eigth Eilat Conference on New Antiepileptic Drugs (AEDs)-EILAT VII, took place in Sitges, Barcelona from the 10th to 14th September, 2006. It could be the The rash was pruritic and generalized; it consisted of irregular, ill-defined macular erythema in patches with superimposed follicular papules and massive edema of the face and periorbital region. While the cause of the erythrophagocytosis This spongy tissue inside bones is where blood cells are produced. FOIA Expert opinion: Carbamazepine and oxcarbazepine are the most common AEDs which induce hyponatremia in patients with epilepsy. Interestingly, patients in group I was older than the average of age of most KD patients. AFBN is acute localized bacterial infection of the kidney without abscess formation. Human herpesvirus-6 associated hemophagocytic syndrome in beta-thalassemia: report of one case. However, neither rat nor human liver microsomes catalyzed NADPH-dependent irreversible binding. By evaluating the largest cohort of ICI-related HLH cases, we observed that ICI-related HLH arises with a delayed timing with respect to initiation of ICI treatment, and usually presents without other irAEs and concomitant infections. Küpffer cell hyperplasia with hemophagocytosis in LB is a rare finding; although it does not necessarily denote a complete HS, it is associated with the same underlying disease and/or infection, with a decrease in intrahepatic perforin-positive lymphocytes. A high index of suspicion on the progression from KD to HLH would be mandatory when the KD patients show elevated AST and ferritin and the presence of hyponatremia, and especially so if the patient is of older age. Diagnostic criteria include idiopathic fever, splenomegaly, cytopenias, hypertriglyceridemia, hypofibrinogenemia, and the presence of hemophagocytosis. Cessation of PIPC-TAZ combined with corticosteroid therapy improved clinical symptoms. Hyponatraemia associated with oxcarbazepine is also a problem; however, it is less likely to cause rash than carbamazepine. Rash associated with lamotrigine has typically occurred within the first 8 weeks of treatment. - Causes of pancytopenia - Emergencies associated with pancytopenia - Medications associated with pancytopenia CALCULATORS. An 18-year-old girl presented with maculopapular rash associated with cervical lymphadenopahy appearing 3 weeks after treatment with allopurinol. One month later he suffered from impaired liver function and pancytopenia in the presence of hypocellular bone marrow with hemophagocytosis. Early in 1997, Glaxo Wellcome strengthened existing warnings in the product label regarding the risk of rash and reinforced the importance of adherence to administration guidelines in an effort to reduce the incidence of rash. Cause: It can be caused by environmental factors, such as radiation, microorganisms (especially viruses), some particular drugs, and then it is secondary pancytopenia, because the cause is known. HLH developed a median of 6.7 weeks after initiation of ICI treatment (IQR 2.9–15.4, n = 18, 47%). In these studies, lamotrigine was seen to be well tolerated, to be an effective mood stabilizer, to be significantly more effective in schizophrenia when given as adjunctive therapy to clozapine. Risk factors are young age, concurrent valproate (VPA), high starting dose, and rapid escalation. Felbamate should only be prescribed under close medical supervision because of aplastic anaemia and hepatotoxicity. Chemotherapeutic agents, chloramphenicol, sulfa drugs, gold, nonsteroidal antiinflammatory drugs, certain antiepileptic drugs, ionizing radiation, benzene, and various other drugs have been associated with aplastic anemia. No evidence of infection was evident. Rare cases of behavioural ADRs and IgA and IgG2 deficiency associated with the use of zonisamide have been reported. Seizures may also be caused by high fevers and psychological distress. This may prevent bleeding or organ damage. Both veratrine and potassium evoked a marked release of glutamate and gamma-aminobutyric acid (GABA), with a more moderate release of aspartate. Secondary HLH is a condition that can occur after strong immunologic activation, such as infections, autoimmune diseases, and malignancies, and is associated with high mortality (Ishii et al. Most of the anti-cancer and anti-viral drugs cause pancytopenia, as they directly target the cells. …one cause of pancytopenia.Treatment of a disorder that causes pancytopenia (eg, chemotherapy for an underlying lymphoma) may further exacerbate cytopenias. Hemophagocytic lymphohistiocytosis (HLH) is a rare life-threatening multisystem disorder. Intravenous immunoglobulin and steroid were administered with discontinuation of lamotrigine; the hemogram and liver function profile improved dramatically. Anti-epileptic drugs are one of the most common classes of drugs implicated in DRESS. However, relatively few patients so far have been exposed to this drug, and therefore more postmarketing information is required. An 8-year-3-month-old male with right porencephaly and epilepsy was found to have skin rash 2 weeks after the beginning of treatment with lamotrigine. adult bearded dragon (Pogona vitticeps) that had a massively elevated white blood cell count (158×109/l) due to an increase in circulating azurophils with approximately 12% of these cells exhibiting erythrophagia. Conventional treatment for absences was effective in only two children. However, antiepileptic drug-related hemophago- This is the first HLH report of an association with oxcarbazepine. However it requires medical attention when combined with other antipsychotics except for clozapine due to possible iatrogenic worsening of psychiatric symptoms. This person is not on ResearchGate, or hasn't claimed this research yet. Along with epilepsy, it has become the treatment of choice in many areas of medicine, including various psychiatric disorders and pain syndromes. Topiramate frequently causes cognitive ADRs and, in addition, also appears to cause word-finding difficulties, renal calculi and bodyweight loss. Urine contained [(14)C]lamotrigine (4.5 +/- 0.5%) and [(14)C]lamotrigine N-oxide (0.9 +/- 0.2%). Lamotrigine has been reported to have positive treatment effects for other potential clinical applications in limited number of reports. The metabolites of [(14)C]lamotrigine (78 micromol/kg, iv) in adult male Wistar rats were characterized with particular reference to thioether derivatives of an epoxide intermediate. Dermatologists should consider the possibility of HLH in any patient presenting with fever, rash, internal organ involvement, and cytopenia. A comparative analysis was performed for fever duration, presence of cytopenia, serum ferritin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), triglyceride, fibrinogen, hyponatremia, reactivation, and survival rate in those HLH patients associated with KD (group I) and other causes (group II). HLH of our patients was probably induced by PIPC-TAZ, as judged by the timing of the onset of HLH and the positivity of the drug-lymphocyte stimulation test. There are increasing reports of HLH in patients who underwent autologous or allogeneic stem cell transplantation (SCT) or solid organ transplantations [4,10,19,23,55,56]. Der jetzige Vorschlag überzeugt durch einen pragmatischen Ansatz und führt neue Konzepte nur dort ein, wo neue wissenschaftlich belegbare Befunde vorliegen. Patients on LTG also had significantly lower VPA levels, but this effect was only minor (-7%) and most probably not of any clinical relevance. the first 8 weeks of treatment [10]. So far, only anecdotal cases of sHLH associated with multiple myeloma have been published. GS2 is caused by a gene mutation involving RAB27A, which affects a melanosome anchoring complex in melanocytes and releases cytolytic granules from T cells and natural killer cells. Hepatomegaly, lymphadenopathy, neurological symptoms, edema iii. More than 150 years after bromide was introduced as the first antiepileptic drug, adverse effects remain a leading cause of treatment failure and a major determinant of impaired health-related quality of life in people with epilepsy. This does not treat pancytopenia. A heritable defect in response to arene oxides thus may predispose some patients to phenytoin hepatotoxicity. The effect of LTG has been compared with that of phenytoin, on the release of endogenous amino acids and radiolabelled acetylcholine evoked by veratrine or potassium, from slices of rat cerebral cortex in vitro. Thus, the authors conclude that the effect of LTG on VPA concentrations is not of clinical relevance. Acquired or secondary hemophagocytic lymphohistiocytosis (sHLH) is a life-threatening hyperinflammation syndrome caused mostly by various infectious agents, autoimmune disorders or malignancy. Hemophagoytic lymphohistiocytosis (HLH) is a rare life-threatening disorder caused by overactivation of the immune system, associated with infections, autoimmune disorders, and malignancies. Therapy of any HLH form is based on suppression of the hyperinflammatory status by destruction of activated CD8+ T lymphocytes and macrophages, and treatment of any existing HLH triggers. Clipboard, Search History, and several other advanced features are temporarily unavailable. An 8-year-3-month-old male with right porencephaly and epilepsy was found to have skin rash 2 weeks after the beginning of treatment with lamotrigine. Although pancytopenia is a rare presentation of tuberculosis, it should always be considered in patients presenting with pancytopenia, unexplained pyrexia and weight loss. We aimed to report this case in the literature and make physicians aware of the uncommon symptoms of this syndrome when they prescribe antiepileptic medications in particular. In one case the rash progressed to include follicular pustules and resolved with superficial desquamation. Moreover, viral serology tests were negative. This site needs JavaScript to work properly. haemophagocytic syndrome. An approach to the patient with drug allergy; Aplastic anemia: Pathogenesis, clinical manifestations, and diagnosis Anfallsform, Art der Epilepsie, Einteilung des Epilepsiesyndroms, Ätiologie und Komorbidität sind die wichtigsten Bestandteile. It is effective for a variety of seizure types in adults and children both as an add-on agent and in monotherapy, and is generally well tolerated. Haematological side effects such as anaemia, mild thrombocytopenia and leukopenia are uncommon and do not usually require cessation of the drug .. Die aktuelle Klassifikation der Epilepsien aus dem Jahr 2017 gleicht stark der Version des Jahres 1989. In clinical trials, this has most often been limited to a simple morbilliform rash which is not associated with evidence of systemic involvement. Hemophagocytic syndrome associated with antiepileptic drug. © 2008-2021 ResearchGate GmbH. One recently diagnosed patient continues to have frequent myoclonic absences. or skin rush could also be present. In patients in group I, a higher level of reactivation (20%), a lower survival rate (P = .001), higher AST (P = .031) and ferritin (P = .005), and frequent hyponatremia (P = .000) were found compared to patients in group II. Methods Introduction Hemophagocytosis refers to the pathologic finding of activated macrophages engulfing erythrocytes, leukocytes, platelets, and their precursor cells [ Patient 1 presented with seizures and neurological compromise, whereas patient 2 presented with pancytopenia and diarrhea. The analysis of variance revealed a significant effect of enzyme-inducing comedication (as expected) and age on the VPA LDR. Keywords: Fever, Rash, Lymphadenopathy, Pancytopenia Background Anticonvulsant hypersensitivity syndrome (ACHS) is a rare but potentially fatal complication that is associated with aromatic antiepileptic drugs [1–4]. The present case demonstrates development of pancytopenia associated with levetiracetam in an infant. tuberculosis is known to cause pancytopenia. During the follow up, two years later there was no lymph gland enlargement, skin rash, or other signs. Drug hypersensitivity syndrome is among the most severe drug hypersensitivity reactions and in rare cases it may progress to hemophagocytic lymphohistiocytosis. For 10 days he had a fever, hepatosplenomegaly, rash, edema and other systemic symptoms. It was not associated with hepatotropic viral infection, alcohol-related chronic liver disease, or autoimmune chronic liver disease. Epub 2010 Apr 1. Herein, we report a case of allopurinol-induced drug reaction with eosinophilia and systemic symptoms complicated by hemophagocytic lymphohistiocytosis. Apart from elevated titer of Adenovirus serology, other laboratory findings and bone marrow histology were within normal limits. 2019 May 2;7(1):117. doi: 10.1186/s40425-019-0598-9.
